Guys, if you done all those tricky parts, you still can see the gap between the Main bottle and it Cup. Now.. with some modification of shapes, you definitely could cover that up nicely.

Here I will show you how I put something there to do it. Prepare this first.. Set your Foreground with this #9fa5b0 color. Create a new layer above the Background layer. Create a selection like the image above told you and fill it with that color!

Step 6 - Bottle Sealed

Next to me I do is, adding the Sealed portion of the bottle. First thing first, for this procedure, I'll start by placing two base line in different layer. To do this, press Ctrl + N to create New Layer, Draw a simple line on this layer by pressing the U key on your keyboard. Pick the Line Tool from the menu, Draw it! Just like as shown in Fig.

Add the style of this layer by Right-Clicking it than choose Blending > Bevel and Emboss.

Again you'll gonna need the New Fill or Adjustment Layer. To do so.. click its button than to fill the line with a Light Blue (#74a8eb) color like I did. If you're done.. Duplicate the line by Pressing Ctrl + J! Don't forget to copy the layer style as well as the first line. Now you have two line on the Cup of your bottle with two different Light Blue (#74a8eb) color fill adjustment. Do the clipping mask to both of them!
